A friend tightened the lockring without the cassette on, and now we can't use the chain whip to unscrew it. It's on a road bike wheel if that matters. I'm looking for tools and ideas to undo this.

I found this post on a forum, but I'm looking for more answers https://www.lfgss.com/conversations/303374/

    Can you remove the freehub from the hub with the lock ring in place? This opens a heap of options. Carefully grind or mill the lock ring down to remove the lip, so you can slid a cassette on. Fabricate a tool that will clamp around the freewheel and mesh with the splines.

Pad the freehub body with rags, hold it with a big pipe wrench or vice grips.

Another possibility is holding the freehub body pointing downwards in a vice with plastic soft-jaws (or padded with rags, again). If you position the freehub at the side of the jaws you can probably get the lockring tool in underneath.

    I'd look at sliding pliers, aka plumbers pliers around the freehub body, and a lot of padding. The freehub is likely steel and will cope with this force.

  • It's probably worth degreasing the freehub first. Clean and dry, a ruined inner tube is good for soft jaws or wrapping round the freehub. Cable ties can secure it if they don't get in the way of the pliers

  • A thick piece of leather from a discarded belt is probably better than rubber, less shearing.

Use a strap wrench on the freehub body.
